Just to be clear, I used a house air purifier (negative ion generator), not an ozone generator. Whether or not the former generates the later, and how much, is another open question that emerged during the thread.

Thanks dannyboy60 for comprehensive post on ozone. Do you know of any study that shows house air purifiers (aka ion generators) produce a significant amount of ozone hence they should be avoided? After all they are designed to be used in house.

How bad is ozone for health?

Thanks JohnDoee for the informative link. So I followed the chef's advice:

Sorry English is not my native language. By frusty I mean 'white resine being created around the buds'.

How are you so sure JD? After all the the ions attache themseles not only to aerosol in the air but to leaves too. What guaranees that they somehow don't affect the plants behavior?

I have put a nagative ion generator (Ionic Air Purifier HF-100) in my grow tent (60x60x90cm) to neutralize smelly particles in the air that may skip the tent. I should say it is quite effective in combination with a Rhino filter. to the extent that I hardly can smell anything even when I...

I agree with both of you above. But the topic's main question here is HOW to make a CO2 bag.

CO2 bags are a less-kown non-hazardous method of supplying CO2 to plants. The bags consist of a type of fungus called mycelium in a nutrient ambient. When the fugnus grows, it generates CO2 until it exhaust all the nutrients. Sounds pertty simple to set up. So I am wondering how effective...

I have just made my first harvest. Now wondering what can be done with the remaining leaves ans stems? Can I make hash from them? How? Does it worth the effort? peace :leaf:

Interesting. What kind of filtering do you use along with the pc fan?

I ended up buying a S&P TD 350/125 silent 5" fan with a Rhino filter. But since 165-224 cfm of the fan is too much for my 12' tent, I prefer to reduce the speed, hoping that this also reduce the noise. It is stated in the fans catalogue that the noise is 20db from 3m, which is the most quiet...

I was thinking about making a DIY filter and even bought the active carbon. But I guess it never become as good as factory made. That's great that you could make such a silent tent. How is your ducting settings mate? Do you use a duct muffler, speed controller etc? I looked at ebay for Vertex...

Hi dudes, Noob would-be-grower here. I live in a small flat and when my neighbour listens to music, I do to! So having quietest fan and best active carbon filter are crucial to me. First I thought I use computer fans but apparently they are not able to suck enough air from carbon filters...
